ADJUSTABLE REGISTER BOX 0R HEAD.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed November 23, 1910. Serial No. 593,903.

T 0 all whom it may concern:

Be it known that I, JACOB PFEFFER, citizen of the United States, residing at WVater- 100, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Adjustable Register Boxes or Heads, of which the following is a specification.

My invent-ion has for its primary object the provision of an adjustable register box or head for heating systems, said box or head being formed in sections, thus permitting the parts to be easily packed for ship ment, easily diassembled and reassembled and easily adjusted to suit the circumstances of any particular case.

A further object of the invention is to so form the sectional head that the main body of the head may be set in place with its front edge projected to the plaster line and that the face section of the register, including the register grid, may be afterward put in place and engaged with the body during the work upon the building or after the building is completed.

Still anotherobject is to provide, with the sectional head, a section having a slip oint engagement therewith which may be either used as a boot for first floor registers or as an increaser or reducer for second floor registers, or may be entirely removed if direct connection is desired.

My invention is shown in the accompanying drawings, wherein:

Figure 1 is a longitudinal vertical section of a register head or box on the line 11 of Fig. 3. Fig. 2 is a transverse section on the line 22 of Fig. 1. Fig. 3 is a vertical section on the line 83 of Fig. 2. Fig. 4 is a perspective view of the rear section of the head or box. Fig. 5 is a perspective view of the front section of the head. Fig. 6 is a perspective view of the section which may be used as a boot, an increaser or reducer, and Fig. 7 is a detailed section on the line 7-7 of Fig. 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring now to these figures, 2 designates a register plate of any suitable or desired character and construction, having the exterior marginal flange 3 extending around three sides of the register plate, but not across the bottom edge thereof. This plate 2 has also the inner flange l which extends around all four sides of the central open work grid 5, such as is usually found in register plates. A damper 6 is pivotally mounted on the inside of the face plate of the register and is operated by means of a lever 7 pivoted at 8. By means of this lever 7 the damper may be moved to any desired position, as for instance the position shown in dotted lines in Fig. 1, or the damper may be closed to the position shown in full lines in said figure. I do not wish to be limited to any particular form of damper plate.

Attached to the inner face of the register plate 2 is a rectangular sheet metal boxing or frame having the three sides 10, 11 and 12 which define three sides of a centralopening. These sides of the frame fit snugly over the flange 4:. The sides 11 and 12 of the frame or boxing extend downward beyond the lower edge of the plate 2 as at 13, as shown particularly in Fig, 5. The sides 10, 11 and 12 of the box are all three outwardly flanged as at 14, these flanges fitting in the space between the flanges 3 and 4 of the register plate 2. The flanges are held in engagement with the inner face of the plate 2 by means of bolts 15. Extending transversely across between the downward extensions 13 of the flanges 11 and 12, and disposed below the front plate 2, is the apron 16. This apron is flanged at its upper edge as at 17, the edge of the flange being overturned to stiffen it. This flange 17 fits against the flange 4 on the register plate 2 which extends transversely across the plate below the grid thereof. The ends of the apron are folded over as at 19 to interlock with flanges 18 which are formed upon the outside edges of the extensions 13, this interlocking fold having the form shown in the detail section Fig. 7. By this means the apron is connected with the extensions 13 of the frame or box. Attached to the inner face of the apron is a transversely extending strip 20 which is spaced from the apron to provide a socket for the reception of the margin of a boot section to be hereafter described. Preferably this transverse a sheet metal box 23 having three sides, 24, 25 and 25. The end margins of tlfese sides 25 and 25 are folded over as at 26 and then refolded upon the body of the material as at 27 to form three pockets 28 extending longitudinally along the sides 24 and 25, these pockets being designed to receive the sides 10, 11 and 12 of the front section of the box or head and form a slip oint therewith as plainly shown in the upper portion of Fig. 1, wherein the side 10 of the frame is shown as inserted within the pocket 28 extending along the side 24 of the box 23. It will be seen that the slip oint thus formed permits the front section of the head to be easily slipped into and out of engagement with the body portion of the head.

The rear side 24: of the box 23, at its lower end, is provided with a transversely extending pocket 31 to receive the upper margin of the boot section. In detail a folded strip 30 is soldered or otherwise attached to the rear face of the box 23 opposite to the strip 20, as illustrated in the lower part of Fig. 1. The section 32, which is shown in detail in Fig. 6, may be either used as a boot for a first floor section or as a reducer or increaser for the registers of other floors. This sec tion consists of a rectangular box, open at its ends, formed of sheet metal, the lower margin of the box being folded over upon itself as at 33 to strengthen the lower mar gin. This rectangular section, as shown in Fig. 1, is adapted to be inserted within the head and its front and rear sides are adapted to be received within the pockets formed by the strips 20 and 31, as is also illustrated in Fig. 1. It will thus be seen that these strips 30 and 31 provide for a slip joint between the section 32 and the head. The upper end of the box 23 is preferably formed with an opening 35, this opening being surrounded by an upstanding flange 36 whereby a pipe extension 37 may be attached. In order to provide means for attaching the box 23 to studding, I attach to the outer faces of the members 27 the folded strips 38, these strips being formed with perforations 39 for the passage of bolts. These bolts connect the strips to the studding A to which the laths B are applied, 0 indicating the plaster which is placed over the lathe and whose outer face is level with the outer margins of the strips 27, as previously described.

It will be understood that my invention is adapted to be used with registers of any style, capacity or profile and that they may be constructed to conform to any desired conditions or to the dimensions of the timber used in the construction of the building. The box 23 is first placed in position with its front edge projecting to the plaster line, the front of the head being of course removed. This body portion 23 of the head, constructed as above described so as to permit the front to be removed, permits an even surface to be secured in plastering the wall. As before stated the box 23 is placed in position with its front edge projecting to, but not beyond the plane of the plaster, and the plaster may be applied directly up to the front edge of the box 23. Thus no open spaces are left between the head and the wall as is frequently experienced where the register head projects beyond the plaster line, thus making it difficult to obtain an even surface. The front section may be attached to any desired register plate and may be placed in position at any time during or after the building operations are completed. It permits also the easy removal of the front of the register whenever desired. The section 32, as before stated, may form an increaser or reducer for second floor registers according to the dimensions of the wall pipe used, or form a boot for a first floor register. If direct connection of the wall pipe with the head is desired, then the section 32 is not used. All the parts of this head when properly assembled are firmly held together, and the head in its assembled condition may be shipped or stored until ready for use, thus avoiding the confusion frequently experienced in assembling the different parts.

lVhile I have shown certain details of construction which I believe to be preferable, I do not wish to be limited to these details, as it is obvious that many changes might be made without departing from the spirit of my invention.

Having thus described my invention, what is claimed as new is: V

1.
